置。A dome shape is formed on the bottom of the container by pressurizing and moving a punch that enters the container to be formed toward a bottom punch and a bottom wrinkle holder, wherein the bottom crumple holder is opposed to the bottom of the container. An air injection hole is opened in the part to remove coolant adhering to the bottom of the container, increase friction between the container and the bottom wrinkle holder during pressure molding, and reduce the load on the bottom wrinkle holder. A pressure vessel bottom forming device constructed as follows.
